I have this AutoKey script bound to Meta+S to take the current/last selected text and open it. If it's a URL (starting with https://, rtp://, m3u://, etc.), it will be opened with xdg-open. Otherwise, it will plug the query into Google as a search.

Open Selected.py

import re
import subprocess
import os

text = os.popen('xsel').read()  # grab selected text
url_pattern = re.compile(r'^[a-zA-Z][a-zA-Z0-9+.-]*://\S+')

if url_pattern.match(text):
    subprocess.run(['xdg-open', text])
else:
    # replace spaces with + for URL encoding
    query = text.replace(' ', '+')
    subprocess.run(['xdg-open', f'https://google.com/search?q={query}'])
